Abstract

We developed A/PR/8/34 (PR8) virus-based reverse genetics system in which six internal genes of PR8 and attenuated hemagglutinin and intact neuraminidase genes of field avian influenza viruses (AIVs) have been used for the generation of highly productive recombinant vaccine strains. The 6+2...

Abstract

Vegetable producers are often concerned about potential herbicide carryover and injury to vegetables following the application of livestock manure/compost from animals fed with treated hay. A greenhouse study was conducted to evaluate the effect of activated charcoal on soil residual activity of...

Abstract

The aim of the study was to evaluate carotenoids and tocopherol plasma concentrations in steers and their subcutaneous fat colour at slaughter as tracers of forage-feeding. During winter, 2 groups of steers were ad libitum fed a total mixed ration for 138 days. At mid-April, both groups were turned ...

Abstract

Genotype by environment interaction (G × E) effects for lactating cows' fertility traits may differ with lactation number when accounting for herd production level. Our objective here was to investigate the genetic correlations among three fertility traits in cows and lactation persistency within...

Abstract

Rumination time is a relevant marker for health evaluation. The use of rumination monitoring systems can decrease labor costs when measuring rumination time. The objectives of this study were to: (i) validate the Hr-Tag rumination monitoring system for estimating rumination time in Zebu calves...

Abstract

Genetic drift, loss of heterozygosity and decrease in genetic variability are consequences of high rates of inbreeding over generations.. High density single nucleotide polymorphisms arrays offered new possibilities to estimate inbreeding coefficients more accurately than those from pedigree...

Abstract

Animal welfare is an important aspect of organic broiler (OB) production which involves e.g. up to twice the rearing period compared with conventional production and feedstuffs without prophylactic additives or synthetic amino acids. As market demand for organic broiler meat increases, the formerly ...

Abstract

The nutritional quality of lambs may be improved with increased stearoyl-CoA desaturase (SCD) gene expression, which increases the desaturation of stearic acid to oleic acid. The aim of this study was to evaluate the effect of the rs412429481 (FJ513370: g.31C > A) SNP located at the SCD gene on...

Abstract

Genetic improvement programmes should incorporate emerging challenges about environmental concerns into breeding goals. The large volume of pig meat production implies important greenhouse gas (GHG) emissions despite its lower carbon footprint per animal in front of ruminant productions. The...

Abstract

Freemartinism is a disorder of sex development (DSD) caused by the formation of placental anastomoses between fetuses of different sex. It leads to development of an abnormal reproductive tract in the female fetus, including the presence of testes or ovotestes. In pig production, such conditions...
